Title: Method and apparatus for the measurement of the volume the rate of delivery and the rate of consumption at a given adjustable pressure of liquid fuel for a piece of equipment installed and in operation
IPC: G01M13/00
Filed: 1974-06-26
Abstract: 1480835 Measuring liquid fuel SUD EST ELECTRO-MECANIQUE 26 June 1974 [16 July 1973] 28459/74 Heading G1R In apparatus for measuring the volume, delivery rate and consumption rate of liquid fuel, for example by a boiler or a carburetter, a three-way cock G 1  directs liquid to flowmeters R, Q and R 1 , Q 1  either from a feedpump through a connection III or through a duct 20 from an auxiliary tank A 1 . A valve G is linked to the cock G 1  so that when liquid is being taken from tank A 1  a valve B is closed by air-pressure from a source IV via leads 26, 30 to isolate tank A 1  from a discharge tank A. The compressed-air supply IV passes through an adjustable pressure reducer K to pressurize the tank A 1  and a graduated test cylinder M is equipped with a device automatically zeroing the liquid level using the compressed-air supply. The feedpump may top up the tank A 1  via leads 23, 18 or fill it rapidly via leads 23, 25, 18. Measurements are made with the small-flow flowmeters R, R 1 , large delivery flowmeters Q, Q 1  or with the test cylinder M and pressures are indicated by gauges S, S 1 . In addition to measurements of flow-rate, tests can be made for leakage at the feedpump valve and at a carburetter needle and measurements of the volume of the float chamber of a carburetter. Outlet connections are at I, II and one carburetter V is shown connected to II.

Abstract: 1386536 Coating apparatus HARRIS-INTERTYPE CORP 19 June 1973 [3 July 1972] 28962/73 Heading B2L [Also in Division D1] Apparatus for applying an adhesive comprises a housing 36 for coating material having an applicator 58 associated therewith, a supply tank 22 connected to the housing by conduits 22, 40 for circulation of coating material between the housing and the tank using a pump 28, a heat exchanger 30 being mounted in the conduit 26 to heat the adhesive material and means being provided to heat the roller. The tank 22 is supplied through a ball valve from a main tank. The temperature of the adhesive material is measured in the heat exchanger by means of a sensor and if the temperature is too low hot water which has previously been used to heat the roller 58 is by-passed and on its return to a hot water heater 44 passes through the heat exchanger. Alternatively if the heat exchanger is too hot cold water from a supply 84 is diverted to it to produce cooling. Returning cold water is sensed by a thermostatic valve 88 and dumped instead of returning to the water heater 44. Water used to heat the roller is normally returned via a conduit 70 to the heater 44. More than one roller may be supplied using a parallel system.

[Also in Division B6] A panel for the furniture and building industry is characterised by the panel, which is opaque overall, embodying light reflecting and light refracting bodies of synthetic material which are artificial gem stones or imitation jewels and are arranged in the form of a pattern especially an ornamental pattern and are embedded in synthetic material, especially an unsaturated polyester, so far as the light incident faces thereof. As shown (Fig. 1) the panel 1 consisting of a matrix of unsaturated polyester has a coloured and hardened outer gel covering layer 2 and a back layer 3 and has embedded in it pyramidal ornamental stones 4 of glass having a surface 4<SP>1</SP> exposed and flush with the exposed surface 2<SP>1</SP> of the panel. The stones may be arranged to form a pattern as in Fig. 5. The ornamental stones may be provided with indescent layers by vapour coating in a vacuum and/or with a mirror layer; they may also embody small and if desired interrupted holding edges which may be overlapped by the surface layer or the matrix material in order to secure better anchoring. An outer layer of the panel may be transparent and the embedded elements may be completely covered by the transparent layer. The matrix may include additionally glass-like or coloured grains such as crushed glass, glass fragments or splinters or small natural coloured stones. The panel may be made by applying a parting compound to a backing sheet, placing the ornamental stones on the backing plate in the desired arrangement so that they are held in position by the parting compound acting as adhesive, and applying the plastic matrix to cover the stones completely. Finally the panel is separated from the backing, cleaned and hardened. To increase the strength, reinforcing members may be embedded in the plastic The panel is particularly suited to use as a table top or a tray.

Abstract: 280,527. Pintsch Akt.-Ges., J. Nov. 13, 1926, [Convention date]. Mantles, exchanging.-The alteration in the temperature or composition of the burnt gas occurring when a mantle or the like is damaged or destroyed is utilized for effecting the actuation of mechanism for replacing the broken mantle by a sound one. As shown in Fig. 1, a temperature sensitive element 5 situated above the burner controls a valve 7 admitting gas pressure to a diaphragm-chamber 9 capable of releasing and stopping a mantle-replacing clock train 11. On damage or destruction of the mantle the temperature above the burner drops and the member 5 opens the valve 7 and the mantle is replaced; thereupon the temperature rises again and the clock train is stopped. For utilizing change in the composition of the gases, i.e. mainly their CO, content, an expansible capsule with porous wall takes the place of the capsule 5. According to the Specification as open to inspection under Sect. 91 (3) (a) an operative member, sensitive to pressure, is mounted below the burner.
